In twenty short books, Penguin brings you the classics of the environmental movement.

James Lovelock's We Belong to Gaia draws on decades of wisdom to lay out the history of our remarkable planet, to show that it is not ours to be exploited - and warns us that it is fighting back.

Over the past 75 years, a new canon has emerged. As life on Earth has become irrevocably altered by humans, visionary thinkers around the world have raised their voices to defend the planet, and affirm our place at the heart of its restoration. Their words have endured through the decades, becoming the classics of a movement. Together, these books show the richness of environmental thought, and point the way to a fairer, saner, greener world.
